Installation instructions, only for experts p. 11/22

1. Guide the connection cable for the room sensor through the cable bushing

in the middle of the housing cover. Do not, under any circumstances, guide

the sensor cables through the existing openings at the bottom.

2. The inlet and outlet for the heating system and lighting are fed out at the

bottom of the housing.

3. Connect all cables and lines to the control unit according to the connection

diagram.

4. Reattach the strain reliefs which were loosened under point 4.3. Preparing

the housing on page 9.

There is an ex-works wire jumper at the terminal marked “r” (excess

temperature). This should only be removed if a temperature sensor with

safety temperature limiter is connected. The sensor included in the de-

livery does not have a safety temperature limiter.

Foil sensor: the foil sensor is only required for the operation of infrared

foils and infrared heat plates. If a foil sensor is connected to the control

unit, the maximum cabin temperature is limited to 50° C.

At the “b - b” terminals, a resistor is tted ex-works. This may only be

removed if a foil sensor is connected.

Installation instructions, only for experts p. 12/22

5.1. Removing the front cover

The front cover must be removed to mount the controller on the wall. To do this,

use a at screwdriver.

Once the control module has been mounted on the wall, replace the cover.

● First t the upper edge of the cover into the control unit housing.

●Then press the bottom against the housing until the cover clicks into place

again.

●Insert the screwdriver into the hole provided at the bottom edge of the control

unit.

●The cover is held on by a clip. Press this inwards carefully until the cover

loosens.

●Now remove the cover from the control unit.

6. Final assembly

After all the electrical connections have been made, the control unit can be

mounted.

6.1. Final assembly - surface mounting

To attach the control unit, use the 50 mm screws included in the delivery. Do not

use screws with a larger diameter. This could damage the housing irreparably.

DANGER!

When tightening the screws, be careful not to damage any cables in the

wall. This can lead to severe damage and injury.

Work on the housing must only be carried out with a screwdriver. Using

a cordless screwdriver may cause irreparable damage to the housing.

Installation instructions, only for experts p. 14/22

6.2. Final assembly - recess mounting

For recess mounting the control unit is placed in a wall cut-out section and at-

tached using the 16 mm Torx screws included.

DANGER!

When tightening the screws, be careful not to damage any cables in the

wall. This can lead to severe damage and injury.

EN

Installation instructions, only for experts p. 15/22

6.3. Fitting the sensor

The room sensor is tted in the infrared cabin about 30 cm below the ceiling or

according to the cabin manufacturer's instructions.

●Attach room sensor 1 to the cabin wall using the two 16 mm wood screws

included.

●Lay the 2-pin cable 2 in the cabin wall and secure with cable ties.

CAUTION - incorrect readings: If the room sensor is tted too near

the heater, it will produce incorrect measured values. Maintain a mini-

mum horizontal distance of approx. 30 cm to the heater and approx.

30 cm to the cabin ceiling. Do not t the room sensor above the infrared

heating rods.

7. Adjusting the heating time limit

The heating time limit for the control unit is set at the factory to 99 minutes. This

can be extended up to 24 hours by setting the jumper as described below. The

jumper set is available as an accessory under the order number O-JUMP.

ATTENTION!

For domestic use, the heating time limit may be extended to a maximum

of 6 hours. The provisions of EN 60335-2-53 must be observed for heat-

ing time limits of more than 6 hours.

Heating time settings can only be made to the exact minute for operating

times of up to 99 minutes. From 99 minutes to 9.9 hours, the operating

time can be set with a precision of 0.1 of an hours (6 minutes). After this,

only in 1 hour increments.
